And skb->len equals to size in qrtr_endpoint_post().\nBut size is less than sizeof(struct qrtr_ctrl_pkt) when qrtr_cb->type\nequals to QRTR_TYPE_RESUME_TX in qrtr_endpoint_post() under the syzbot\nscenario. This triggers the uninit variable access bug.\n\nAdd size check when qrtr_cb->type equals to QRTR_TYPE_RESUME_TX in\nqrtr_endpoint_post() to fix the bug."
